TURIBINE.

,Specification of Letters Patent.

Patented Sept. 22, 1914.

. To all whom it may concern Be it known that.I,'O'rro BANNER, a subject of the GermanEmperor, and resident of Easton, in the county of'Northampton and State of Pennsylvania, have 'invented a new and useful Improvement in Turbine- Engines,'of -which the following is a specification. i

' bine engines but is not limited to such use.

Practical embodiments ot' the invention are represented in the accompanying draw ings, in whichl Figure 1 is a view'o'f the engine half in side elevation and half in longitudinal' central vertical section showing one form of inlet, and Fig. 2 is a detail section showing a modified form of inlet.

The engine shaft is denoted by 1, the blade wheels which are fixed thereto by 2, and their row of blades by 3. The casing is provided at its ends with chambers 1 and 5 communicating with their outlets (5 and 7.,

In Fig. 1 the casing is shown as provided with a transversely divided 'chamber 8, 9, communicating lwith the divided intermediate inlet 10, 11, and having the oppositely arranged rows of nozzles 12, 13.

In Fig.` 2'the chamber 14 is shown as undivided and its inlet 15 as undivided, the opposit'ely arranged nozzles 1G, 17, leading from the said undivided inlet chamber.l The transverse partitions carried by the casing and alternating with the blade wheels are denoted by 18 and their nozzles by 19. The

bearings for the engine shaft' are located at the opposite ends of the casing and are refertibly ldivided in a` horizontal plane coincidentwith the axis of the shaft `to' form -upper and lower members 20, 21, and 22, 23,

respectively. l,The casing is preferably divided in a horizontal lane co-inoident with the.y axis of' the'sha t' and in transverse vertical planes to form upper members 24, 25, 26, and lower members 27, 28, 29, the lower members 27 and 29 being provided with brackets 3G, 31, tor supporting the casing and the members 25,28, forming the ring which contains the intermediate inletchamber. 32 which divides the inlet chamber may be formed integral with the ring members 0r attached thereto in an v 1nanner.

Valves 33, 841, are shown in Fig. 1 for independently controlling the admission ofthe motive fluid to the inlet chambers 8, 9, and a valve 35 is shown in Fig. 2 -for controlling the admission of motive iuid to the single inlet chamber 14.

In the accompanying drawings, the turbine engineis shown as provided with four stages upon each side of the motive fluid inlet chamber and the wheels as having single rows of `blades but the number of stages and the numberrof rows of blades may be varied' It will be seen that in a turbine engine constructed as herein set forth, the motive Huid will enter the turbine engine intermedia-te its ends and will pass therefrom toward the opposite ends of the engine where it will be permitted to escape through separate, outlets thus permitting a very ready and rapid exhaust of the motive fluid.

In that arrangement in which the inlet chamber is divided, the admission of the motive Huid may beso controlled as to permit the same to be admitted to one set of wheels while the other set of wheels is turning idly up to a predetermined load and then permit the admission of the motive iiuid to the idly running set of wheels.

What I claim is The partitionI 1. A turbine engine comprising a shaft,

two sets of blade wheels thereon arranged let for driving either of the two sets of blade 'wheels vor both sets of'blade wheels.

2..A double How turbine engine havingoutlets at its ends and an intermediate inlet comprising a divlded ring having nozzles Ato drive the shaft in the same direction, a

through its Wal-1s arranged in position to direct the Huid outwardly to the two elements of the engine, and means for controlling the admission of the motive uid to either one 5 or both sides of said divided-ring.

In testimony, that I claim the foregoing as my invention, I have signed my name in Witnesses EDWARD A. DIETRICH, CHARLES FRUTENEY.
